Hi all, So I've researched this a bit, and the answers I've come up with so far are vague. I'm looking to build small packet radio terminals around the PocketBeagle single-board computers to interface RFID readers being used in horse endurance ride events.
Now, I've read up on the OSD3588 and its embedded TPS65217C. I'm looking to use these cells to power the devices: https://core-electronics.com.au/polymer-lithium-ion-battery-18650-cell-2600mah-solder-tab.html All that's inside the box in addition to this is a MAX3232 level shifter hooked up to UART2/UART4 (the one chip does TX/RX of both UARTs). The aim is to allow the real-time clock in the PocketBeagle to retain time and act as a UPS for the duration of a week-end long event. >From what I've been able to piece together, ideally a thermister is required, and one of the schematics in the TPS65217C datasheet calls out a 10kohm one specifically, along with a parallel 75k resistor. I'm thinking this will be soldered to the negative end tag of the cell and heat-shrunk to the cell body with the output wire from the thermister joining wires from the two ends of the cell. This is the thermister I'm looking at getting: https://core-electronics.com.au/thermistor-10k.html Would this suffice, or are there specific requirements I should be looking for? Also, I hear somewhere that the TPS65217C needs to be configured to enable charging of the LiPo cell: is that already done by the standard BeagleBone/PocketBeagle image or should I be looking at the data sheet for the appropriate I²C commands?
